In the North Atlantic, huge amounts of heat are moving into the Arctic Ocean (green circle right).
At some spots, heat that is traveling underneath the sea surface comes to the surface (green circle at the top).
Most warming caused by people’s emissions goes into oceans, especially into the top layer of oceans.
Furthermore, warmer air and warmer sea surfaces can cause winds to grow dramatically stronger. As the Arctic is warming much faster than the rest of the world, the narrowing difference between the temperatures at the North Pole and the Equator is decreasing the speed at which winds circumnavigate Earth; at the same time, the amount of heat that is moving north can grow dramatically, both due to winds and sea currents, and cyclones can further accelerate this.
The danger is that an influx of warm salty water will reach the seafloor and trigger methane eruptions.
The situation is especially critical in many parts of the Arctic Ocean where the water is very shallow. Some 75% of the East Siberian Arctic Shelf (ESAS) is shallower than 50 m (see maps on the right).
